    摘要: A method and associated apparatus for forming a composite structural member from a charge are provided. The charge can be disposed on a first die of the apparatus and formed to a desired configuration defined by a recess of the die by inserting a second die or a tool into the recess. In some cases, the first die can include two portions that are adjustable in a transverse direction so that the recess can be opened by the insertion of the second die or tool. The second die or tool can be a substantially rigid member or an inflatable bladder. In either case, the charge can be disposed on the first die, formed, and then further processed on the first die, thereby facilitating indexing of the charge for each operation.

    摘要: Tools for manufacturing composite parts and methods for using such tools are disclosed herein. A method in accordance with one aspect of the invention includes manufacturing a fiber-reinforced resin part from a plurality of fibers positioned on a tool having a female mold surface. The mold surface can include a first side region, a second side region, an interior region between the first and second side regions, and transition regions between the first and second side regions and the interior region. The method includes positioning a compaction tool over the mold surface. The compaction tool includes a first pressing device and a second pressing device carrying the first pressing device. The method further includes pressing a first portion of the fibers against the transition regions with the first pressing device without generally compacting the portions of the fibers outboard of the transition regions. After pressing the first portion of the fibers, the method includes pressing a second portion of the fibers against the first and second side regions and shoulder regions of the mold surface outboard of the first and second side regions.

    摘要: A one-piece barrel assembly cart includes a right assembly cart base connected with a left assembly cart base and at least three stabilizer rings that are attached to the assembly cart base. The one-piece barrel assembly cart may be used to stabilize a tapered cured composite barrel, for example the large fuselage barrel of the aft section of a large new generation aircraft, such as a 7E7 Boeing airplane. A modular assembly cart includes at least two identical modules. Each of these modules includes a cart base and a stabilizer ring. The diameter of the inner surface of the stabilizer ring may vary as needed. Other modules including a fuselage support may be added. By providing modular assembly carts any shape and size of a one-piece composite barrel may be stabilized after curing of the composite material.
